Application filed January 30, 1913. Serial No. 745,283.

To all whom it may concern I Be it known that I, FRANCIS M; Jones, a citizen of the United States, residing at Emporia, in the county of Lyon, State of Kansas, have invented certain new and useful Improvements in Adjustable Steel Window- Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in window screens and more particularly to those constructed of steel or other metal.

The primary object of the invention is to provide an improved window screen construction which renders the same adjustable, both as regards the frame and the mesh thereof so that the device may be adjusted to fit Windows of'various sizes.

With the above and other objects in view, the invention resides more particularly in the peculiar combinations and arrangements of parts as will be partly illustrated as a referred embodiment in the accompanying drawings and described in the specification, although the invention is protected for all desirable changes and uses within the scope of the invention as claimed.

Figure 1 is a front elevation of a window screen constructed in accordance with the invention, the same being shown in its retracted position. Fig. 2 is a similar view but showing the device in an extended position. Fig. 3 is a plan View of a section of the wire mesh used in connection with the improved screen. Fig. 4 is a detailed fragmentary view of one corner of the screen .to more particularly illustrate the manner of connecting the corners of the frame sections and of enlarging or reducing the size of the screen or wire mesh part. Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1. Fig. 6 is an enlarged view of a portion of the frame. Fig. 7 is an edge view of the holder for the screen or wire mesh. Fig. 8 is an elevation of a fragmentary portion of the frame to show the manner of adjusting the sections thereof.

In illustrating the preferred embodimentof the invention, the improved adjustable window screen is shown as formed of a steel or metallic frame 10 comprising a plurality of corner sections 11 and 12 respectively, each corner section being formed of sheet met-al'bent to form a substantially rectangular and hollow inclosure. the corners of which are slightly rounded as indicated at 13 and the edges of which are spaced apart as indicated at 14: centrally of the inner sides thereof. Each section 11 and 12-consists of two of such members riveted or otherwise secured at the corners of the frame as indicated at 15 whereby four (4) right angular sections are provided.

The extremities of the respective corner sections are fitted one within the other or telescopically mounted as shown at 16 centrally of the four (4) sides of the frame so that means are provided for extending or contracting the frame to vary its height and length or either, to render the frame adaptable for windows of various sizes. In order to hold the telescoped ends of the respective corner sections in adjusted positions, the outer portion of each section is provided with a longitudinal centrally located slot 17 uvhile a clamping screw or bolt 18 is carried by the inner portion for movement through the slots and for causing the said portions to be held in binding relation and agalnst movement.

The screen or Wire mesh is indicated by the numeral 19 and is engaged at its four (4) edges or sides through the respective slots 14 formed by the spacing of the longitudinal edges of the sections of sheet steel or metal forming the tube parts. This screen or wire mesh has its corners cut diagonally as shown at 20 for a short distance, consistent with the amount of adjustment desired and the adjacent corner portions of the mesh are bent back on the intermediate portions thus provided, as shown at 21, such turned back portions being of substantially triangular form.

The intermediate portions thus provided are engaged around substantially fiat and tubular sheet iron wire holding members 22, which are mounted within the tubular frame sections and which are each formed of two sections telescopically joined as shown at 23 to vary the lengths thereof according to the height andlength or width of the screen. Each of these wire holding members 22 has one extremity disposed through the adjacent corner portion of one of the frame sections as indicated at 24 for the application of a crank or other tool for rotating the same As indicated in Fig. 5 the-wire mesh is engaged around the wire holding members, the intermediate portions formed by the diagonal cuts 20 being engaged with the wire holding and winding members whereby the wire mesh may be varied in size to agree with the size of the frame. When the wire mesh is extended so as to include parts of the triangular portions 21, the edges of the severed or cut portions are secured together to prevent the entrance of flies or other insects and it is of course obvious that the wire mesh maybe renewed at suitable times.

When the wire holding members are wound to the proper extent and their fiat sides are located toward the interior and exterior sides of the frame or sections thereof, screws or pins 25 are engaged transversely through the frame sections near each end of the holding members and outwardly of the latter to hold the same against turning and thereby to hold the wire mesh taut. It will be apparent that the adjustment of the telescoping ends and top and bottom portions of the frame, will permit adjustment of the screen to windows of various sizes within areasonable scope, and that only one section of wire mesh will be required instead of two, thus obviating the entrance of flies and other insects, which occurs with the use of screens having slidable sections.

I claim:

1. In an adjustable window screen, a frame consisting of corner sections, each corner section consisting of sheet metal sections bent in substantially rectangular and hollow form with their edges spaced apart, said latter portions being connected at the corners of the frame, the extremities of the corner sections bein slidably engaged,

means connecting sai latter portions to hold the same in adjusted relation, a section of screen wire having its corners diagonally cut and the adjacent portions rebent on the portions between the cuts and wire holding members rotatable in the frame sides and having the last named portions of the screen wire wound thereon, said wire holdin members being adjustable in length and extended throughthe frame at one end to permit turning thereof.

2. In an adjustable window screen, a frameveonsis'ting of corner sections, each corner section consisting of-sheet metal sections bent in substantially rectangular and hollow form with their edges spaced apart, said latter portions being connected at'the corners of the frame, the extremities of the corner sections being slidably engaged,

means connecting said latter portions to ,60

members rotatable in the frame sides and having the last named portions of the screen wire wound thereon, said wire holding members being adjustable-in length and extended through the frame at one end to permit turning thereof and means for holding said wireholding members against rotation.

In testimony whereof, I affix my signature, in the presence of two witnesses.

FRANCIS. M. JONES.
